煤制乙二醇装置精馏塔器内件形式选择对比

Selection and Comparison of Inner Parts of Distillation Tower in Coal-to-Ethylene Glycol Units

乙二醇作为基础化工原料,在聚酯纤维及防冻剂领域应用广泛。聚酯级乙二醇作为乙二醇的精制品,在聚酯纤维生产中占据核心地位,采用合理的乙二醇精馏技术从粗乙二醇中提取聚酯级乙二醇尤为重要。通过对填料塔和板式塔介绍,选择科学的塔设备组合对于煤制乙二醇精馏工段起着重要意义。

As a basic chemical raw material,ethylene glycol is widely used in the fields of polyester fiber and antifreeze.As a refined product of ethylene glycol,polyester grade ethylene glycol occupies a core position in the production of polyester fibers.It is particularly important to extract polyester grade ethylene glycol from crude ethylene glycol using a reasonable ethylene glycol rectification technology.Through the introduction of packed tower and tray tower,the selection of scientific tower equipment combination plays an important role in the coal-to-ethylene glycol rectification section.
